狀態(tài)欄顏色

調(diào)用系統(tǒng)攝像頭、圖庫吼砂、相冊

一些判斷：
定位權(quán)限逆航、攝像頭鼎文、系統(tǒng)版本渔肩、判斷設(shè)備

ios10權(quán)限

常用宏：顏色、適配拇惋、屏幕尺寸

控件：
scrollview:滑動方向周偎、隱藏滑條、某個方向的彈性

cell:cell內(nèi)數(shù)據(jù)撑帖、分割線起止位置蓉坎、注冊、選中效果

UItableview:策劃刪除胡嘿、隱藏空數(shù)據(jù)cell蛉艾、滑動到指定行

UItoolbar:彈性撐開效果

UIButton:點擊陰影效果、點擊效果衷敌、選中狀態(tài)切換

顯示隱藏文件:

defaults write com.apple.finder AppleShowAllFiles -bool true

隱藏隱藏文件:

defaults write com.apple.finder AppleShowAllFiles -bool false
開啟本機服務(wù)器:

sudo apachectl -k start
sudo apachectl -k restart
顯示日歷：

不進入睡眠狀態(tài)：

caffeinate -t 3600

釋放內(nèi)存：

隱藏指定文件：
如果你想讓某個文件或文件夾影藏，那么chflags命令可以實現(xiàn)面氓。你只需將文件路徑填對即可兵钮，比如我們向隱藏桌面上的macx文件夾蛆橡。如果你想再次看到文件夾，只需將hidden改為nohidden即可掘譬。

chflags hidden ~/Desktop/macx

創(chuàng)建密碼保護zip：
-r 包含子文件/文件夾
-e 加密
-m 壓縮完刪除原文件
-o 設(shè)置所有被壓縮文件的最后修改時間為當前壓縮時間

zip -e protected.zip ~/Desktop/macx.txt
文件夾：
zip -r -e 破解.zip ~/desktop/破解
直接加密：

>狀態(tài)欄顏色

1在Info.plist中設(shè)置UIViewControllerBasedStatusBarAppearance 為NO
2 在需要改變狀態(tài)欄顏色的ViewController中在ViewDidLoad方法中增加：
[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

如果需要在全部View中都變色泰演，可以寫在父類的相關(guān)方法中，或者寫到AppDelegate中葱轩。

>判斷定位權(quán)限

##UITextView
###UITextView假placehold
    placehoderlab=[[UILabel alloc]initWithFrame:CGRectMake(5,5+2, 170, 20)];
[sencedestext addSubview:placehoderlab];
placehoderlab.text=@"請輸入您的需求";
placehoderlab.font=lhw_font(15);
placehoderlab.textColor=lhw_cccccc_graycolor;

#pragma mark textview代理
- (void)textViewDidBeginEditing:(UITextView *)textView {
if (sencedestext.text.length<1) {
    placehoderlab.hidden=NO;
}else{
    placehoderlab.hidden=YES;
}
}

- (void)textViewDidEndEditing:(UITextView *)textView {
if (sencedestext.text.length<1) {
    placehoderlab.hidden=NO;
}else{
    placehoderlab.hidden=YES;
}
}

-(void)textViewDidChange:(UITextView *)textView{

if (sencedestext.text.length<1) {
    placehoderlab.hidden=NO;
}else{
    placehoderlab.hidden=YES;
}

}

###UITextView限制輸入文字數(shù)量
    if (sencedestext.text.length>500) {
    sencedestext.text=[sencedestext.text substringWithRange:NSMakeRange(0, 500)];
}
